What: assume that more than 90% of the exploratory tables and graphs will never be shown to your audience.

Why: in order to find some gold in the mud you need to spend many hours building visualisations to better understand your data. It is key to detach yourself from your work and select objectively only the visualisations aligned with your story and objectives.

How: ask yourself “does my story work if I drop this plot from my presentation / document?”. I know, it hurts… You spent four hours dedigning that beautiful stacked bar plot and then you realised that the actual story was not that… You still want to show off, it’s so cool. Don’t. Focus on your objetive. Remove noise!
